you just can’t do that by yourself…
the reason why upload limits is 10mb is to reduce the hardware costs, so that infinityfree.net can continue providing free hosting services…
if you liked it and want to increase your upload limits consider upgrading to paid plans.
you can use ftp clients like filezilla to transfer data above 10 mbs but note that the max. file size can still can’t exceed 10mb.
see this How to upload files using ftp ? for reference .
